unwieldiest
Hardest to handle
Unwieldiest is the superlative form of unwieldy—the most awkward, cumbersome, or difficult to handle.
Something unwieldiest among a group is the hardest to manage due to its size, shape, or complexity: The grand piano was the unwieldiest piece of furniture to move.
The word applies to both physical objects and abstract things like bureaucracies or arguments.
